CHARLES L. BAUDER, OF CLEVELAND, OHIO IMPROVEMENT IN TRAVELINGINVALID-CHAIRS.

Specification forming part of Letters Patent N0. 40,547, dated November10, 1863.

T0 aZZ whom it may concern.-

Be it known that 1, CHARLES L. BAUDER, of Cleveland city, Guyahogacounty, State of Ohio, have invented new and useful Improvements inTraveling Invalid-Chairs; and I do hereby declare that the following isa full and exact description thereof, reference being had to theaccompanying drawings, and to letters of reference marked thereon,making a part ofthis specification.

The nature of my invention consists in a s ring-lever, E, to hold andlock the seat when extended also, a series of three drivingwheels, K, ona front axle operated by a crank and cog gearing; also, the twoguide-wheels operating on pivots at the back corners of the chair (movedby the arm of chair) from right to left or in a circle.

. Figure 1 represents a side view of the chair; Fig. 2, the guide-wheelsand their jointed connecting-rods; Fig. 3, the front driving-wheels andtheir gearing devices.

A represents the back of the chair, and B the seat and cushion, the backbeing connected by a joint, 0, near the top of the arm,

and also connected with the seat at the joint 1), for the purpose ofregulating the inclination of the back and extending the seat B forward,which the invalid does by bearing his weight against the back of thechair and drawing upward with his finger the lever E, while the oppositeand bent end ofleverE falls out of the aperture G, (in side of seat,)there being five or six apertures, and the spring H holds the lever E inany one of the apertures, holding the lever as a lock.

J is a jointed lever and crank attached to the one end of the axle ofthe front wheels, K, so that the speed of the chair may be increased atany time when required; L, the handle or front legs of the chair, andthe center wheel K is slightly larger than the two outside wheels K, sothat the chair may travel easier and accommodate itself to theunevenness of the floor.

The guide-wheels R operate in the back legs or corners of the chair by apivot, S, that ex tends from the top of the support T. From the top ofeach support T is a short projecting rod, U, jointed and connected to adoublejointed cross-rod, V. At the center joint of rod'V a parallel rod,WV, is attached, which extends upward andis fasented to the movable armX, and as the arm ismoved with the motoin of the hand slightly to theright or left the jointed rods U, V, and W move to the right or left,and guide the wheels It accordingly.

What I claim as my invention, and desire to secure by Letters Patent,is-

1. Thelockinglever E, for holding the chair at any inclination orextension required.

2. The mode of propelling the chair by the arrangement of thedriving-wheels K and their cog-gearing, as herein described.

3. The manner of guiding the movement of the chair in any direction bythe guide-wheels and their jointed rods, as herein described.
